7. Chlorophthalmus Bonaparte. 



(BONAPARTE, Fauna Italiana Fasc. XXVIII, Pesci, 1840). 



Rather elongate and compressed behind. Head rather long, 

 pointed and somewhat depressed. Mandible protruding beyond 

 snout. Cleft of mouth slightly oblique, bordered above by 

 the intermaxillary, the maxillary, which is posteriorly dilated, 

 lying above it; a single supplemental bone present. Eyes 

 large, lateral. Scales moderate, adherent, cycloid, ctenoid or 

 even pectinated, arranged in regular transverse rows, overlap- 

 ping in such a manner as to resemble oblique plates upon 

 the sides. Lateral line present. Dorsal surface of head naked. 

 Dorsal short, its origin before middle. Anal short, opposite

 in narrow bands on the jaws, palatines and in two separate 

 patches on the vomer; usually minute teeth on the tongue.
